SPECIFICATION forming part of Letters Patent No. 730,302, dated June 9, 1903. Application filed February 1, 1902. Serial No. 92.151. (N model.)

T0 at whom it may concern.-

Be it known that 1, WILLIAM S. SCALES, of Boston, in the county of Suffolk and State of Massachusetts,have invented certain new and useful Improvements in Clocks, of which the anism is employed.

The invention will now be fully described by reference to the accompanying drawings, and the novel features thereof will be particularly pointed out in the claims at the close of the specification.

In the drawings, Figure 1 is a diagrammatic rear elevation of a clock embodying the invention. Fig. 2 is a plan of Fig. 1 looking up from the under side. Fig. 3 is a detail elevation of the winding-gear. Fig. 4 is a section on line 4 40f Fig. 3. Fig. 5 is a plan of the actuating-magnet. Fig. 6 is an enlarged detail View of the circuit making and breaking mechanism. Fig. 7 is a section on line 7 7 of Fig. 6. Fig. 8 is a perspective View showing gears 17 and 18 and the gears with which they cooperate.

The escapement-wheel 1 is connected by a train of wheels with the center arbor 2 in any common and well-known way. Mounted on the arbor 2 is the wheel 3, which engages The fly 6, which is connected with the striking mechanism, is connected by a train of wheels in well-known way with idle wheel 7, which engages a pinion 8, which is loose on shaft 5. Loosely mounted on shaft 5 is a lever 9, carrying pawl 10, which engages with ratchetwheel 11. Ratchet-wheel 11 is also loosely mounted on shaft 5 and is flexibly connected with said shaft by a spring 12, one end of which is connected with said ratchet-wheel and the other end with a disk 13, which is fixed to said shaft 5. -Wheel 14 is also rigid on said shaft 5. Between'wheel 14: and disk 13 are the wheels 15 and 4:, wheel 15 being fast to wheel 4 and therefore loose on shaft 5. Rigidly connected with pinion 8 is disk 16, which is also loose on shaft 5. Mounted upon disk 16 are two planet-wheels 17 18, which engage with each other, pinion 18 engaging with pinion 14 and pinion 17 engaging with wheel 15. Motion of ratchet-wheel 11 communicates motion topinion 4 on the timetrain continuously through the planet-wheels 17 and 1S and wheel 15 and communicates motion to pinion 8 on the strike-train intermittently at the proper time through the planet-wheels 17 and 18 and disk 16, which is rigidly connected with pinion 8.

Pawlcarrying lever 9 is connected by rod 19 with lever 20, mounted rigidly on the pivoted armature-shaft 21. Fastened to rod 19 is the weight 22, which tends to draw pawl-carrying lever 9 downwardly, and thus through pawl 10 to communicate motion to ratchet ll. Rigidly mounted on shaft 21 is an armature 23, which is so arranged as to oscillate between the pole-pieces 24 25 of magnet 26. Pivoted on stud 27, projecting from insulated plate 28, is a contact-piece 29, which is electrically connected through insulated plate 28 and wire 30 with one end of the magnet-coil. (Jontact-piece 29 is forked at one end, as shown in Figs. 1 and 6. Finger 33 is bent to one side, as shown in Fig. 5. Projecting from armature-lever 20 is a contact-pin 31, which extends between the two fingers 32 33 of the forked contact-piece 29. When the long arm of lever 20 is lowered by weight 22, it brings contact-pin 31 into engagement with finger 32, but is prevented from making electrical contact therewith by insulation 34. (See Fig. 5.) As said lever 20 continues its movement downward it moves the forked contact-piece 29 until the spring 35, which engages the notched heel of the contact-piece 29, rides over the hump 37, which throws the contact-piece 29 so that finger 32 is disengaged from its insulated connection with the contact-pin 31, and finger 33 is brought into electrical contact with pin 31 away from insulation 34;. Thereupon the circuit is closed, the magnet is energized and brings armature 23 back into line between the pole-pieces, thus moving armature-lever 2O upward and lifting weight 22 and rod 19, which carries with it pawl-lever 9, and the weight is in position to continue its actuation of the clock mechanism. The retaining-pawl 38 prevents ratchet-wheel 11 from rotating are 730,302

backward during that movement, and the maintaining-spring 12 carries the train or trains during the short interval of the raising of the weight 22.

When the armature has approached a position nearly in line With the pole-pieces, the finger 33 of the contact-piece 29 is disengaged from the c0ntact-pin 31 through the action of spring 35, which rides over the hump 37 in the reverse direction from that previously described and breaks the circuit, thereby allowing the weight to carry the armature-lever down again.
